Studies on species composition of phytoplankton in Fuxian Lake of Yunnan, China

It was investigated and analyzed about the species composition of phytoplankton, and their relations to environmental factors sampled in spring, summer and autumn in 2001-2011 in Fuxian Lake (24 degrees 21 '-24 degrees 38 ' N, 102 degrees 49 ' 12"similar to 102 degrees 57 ' 26"E). The phytoplankton from Fuxian lake included 78 species belong to 41 genera 25 family, 7 phyla. Chlorophyta was predominant, with consisted of 43.5% of total species number. Species number of phytoplankton appeared visible monthly variation. The main predominant phytoplankton species was Mougeotia bloodlei, which accounted for 42.94%similar to 84.94% of total cell density of phytoplankton. The community structures of phytoplankton were consist of Mougeotia bloodlei, Chroococcus spp., Cyclotella spp., Ceratium hirundinella and Dinobryon sertularia.
